Determine the Solutions to an Inequality

In this Math Test Prep video, the instructor guides viewers through solving a standardized math test question involving inequalities. The task is to find two values of x that satisfy the inequality 2x + 5.5 < 20. The video evaluates several answer choices, demonstrating the process of substituting values into the inequality and checking their validity. Ultimately, the correct solutions are identified, and the video concludes with a summary of the findings.

What is the inequality that needs to be solved in this problem?

• 2x - 5.5 > 20

• 2x - 5.5 < 20

• 2x + 5.5 < 20

• 2x + 5.5 > 20

Which value of x makes the inequality true for choice A?

• 7

• 9/4

• 5

• 19/2

Why does choice B not satisfy the inequality?

• Because 19 + 5.5 is not a number

• Because 19 + 5.5 is less than 20

• Because 19 + 5.5 is equal to 20

• Because 19 + 5.5 is greater than 20

What is the value of x in choice C that satisfies the inequality?

• 5

• 9/4

• 3

• 19/2

Which two choices are the correct solutions to the inequality?

• B and C

• C and D

• A and B

• A and C
